And it is, I say, an instance of the absorbing tyranny of everyday life, that whenever some such startling incident disturbs its regular tenor of thought and occupation, that same every-day life hastens to bury in its sands the object which has troubled its surface; the more unaccountable, the more prodigious, has been the phenomenon which has scared and astounded us, the more, with involuntary effort, the mind seeks to rid itself of an enigma which might disease the reason that tries to solve it. We go about our mundane business with renewed avidity; we feel the necessity of proving to ourselves that we are still sober, practical men, and refuse to be unfitted for the world which we know, by unsolicited visitations from worlds into which every glimpse is soon lost amid shadows. And it amazes us to think how soon such incidents, though not actually forgotten, though they can be recalled--and recalled too vividly for health--at our will, are nevertheless thrust, as it were, out of the mind's sight as we cast into lumber-rooms the crutches and splints that remind us of a broken limb which has recovered its strength and tone. It is a felicitous peculiarity in our organization, which all members of my profession will have noticed, how soon, when a bodily pain is once passed, it becomes erased from the recollection,--how soon and how invariably the mind refuses to linger over and recall it. No man freed an hour before from a raging toothache, the rack of a neuralgia, seats himself in his armchair to recollect and ponder upon the anguish he has undergone. It is the same with certain afflictions of the mind,--not with those that strike on our affections, or blast our fortunes, overshadowing our whole future with a sense of loss; but where a trouble or calamity has been an accident, an episode in our wonted life, where it affects ourselves alone, where it is attended with a sense of shame and humiliation, where the pain of recalling it seems idle, and if indulged would almost madden us,--agonies of that kind we do not brood over as we do over the death or falsehood of beloved friends, or the train of events by which we are reduced from wealth to penury. No one, for instance, who has escaped from a shipwreck, from the brink of a precipice, from the jaws of a tiger, spends his days and nights in reviving his terrors past, re-imagining dangers not to occur again, or, if they do occur, from which the experience undergone can suggest no additional safeguards. The current of our life, indeed, like that of the rivers, is most rapid in the midmost channel, where all streams are alike comparatively slow in the depth and along the shores in which each life, as each river, has a character peculiar to itself. And hence, those who would sail with the tide of the world, as those who sail with the tide of a river, hasten to take the middle of the stream, as those who sail against the tide are found clinging to the shore.
